SuperBF: Superpixel-Based Bilateral Filtering Algorithm and Its Application in Feature Extraction of Hyperspectral Images

open access: yesIEEE Access, 2019
Bilateral filtering (BF), which is an edge-preserving filtering (EPF) method, has been widely recognized as a simple and efficient approach for hyperspectral image (HSI) feature extraction.

The Bilateral Filter for Point Clouds [PDF]

open access: yesImage Processing On Line, 2017
Point sets obtained by 3D scanners are often corrupted with noise, that can have several causes, such as a tangential acquisition direction, changing environmental lights or a reflective object material. It is thus crucial to design efficient tools to remove noise from the acquired data without removing important information such as sharp edges or ...

Deep Learning-Based 6-DoF Object Pose Estimation Considering Synthetic Dataset

open access: yesSensors, 2023
Due to the difficulty in generating a 6-Degree-of-Freedom (6-DoF) object pose estimation dataset, and the existence of domain gaps between synthetic and real data, existing pose estimation methods face challenges in improving accuracy and generalization.

Point Cloud Reduction and Denoising Based on Optimized Downsampling and Bilateral Filtering

open access: yesIEEE Access, 2020
For the issue of using the center of gravity during down-sampling, some points of their feature will be lost. We propose a new method, FWD(Farthest point Weighted mean Down-sampling), this method uses down-sampling to find the center of gravity, it is ...

Intelligent auxiliary diagnosis of atrial septal defect based on view classification

open access: yes工程科学学报, 2021
Atrial septal defect (ASD) is common congenital heart disease. The detection rate of congenital heart disease has increased year by year, and ASD accounted for the largest proportion of it, reaching 37.31%.

Semi‐guided bilateral filter

open access: yesIET Image Processing, 2017
The bilateral filter (BF) is a non‐linear filter that spatially smooths images with awareness of large structures such as edges. The level of smoothness applied to a pixel is constrained by a photometric weight, which can be obtained from the same image to be filtered (in case of the original BF) or from a guided image (in case of the joint/cross BF ...

A Fast Two-Stage Bilateral Filter Using Constant Time O(1) Histogram Generation

open access: yesSensors, 2022
Bilateral Filtering (BF) is an effective edge-preserving smoothing technique in image processing. However, an inherent problem of BF for image denoising is that it is challenging to differentiate image noise and details with the range kernel, thus often ...

A Refined Bilateral Filtering Algorithm Based on Adaptively-Trimmed-Statistics for Speckle Reduction in SAR Imagery

open access: yesIEEE Access, 2019
This paper proposes a refined bilateral filtering algorithm based on adaptively trimmed-statistics (ATS-RBF) for speckle reduction in SAR imagery. The new de-speckling method is based on the bilateral filtering method, where the similarities of gray ...
